[0060] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are only for illustrating the present invention and do not limit the scope of the present invention. Similarly, the following embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0061] Please refer to Figures 1 to 5. This embodiment provides a device for measuring plant root systems using the water immersion method, including a fixing component 1, a rinsing component 2, a measuring component 3, and a water supply component 4. The fixing component 1 includes a fixing bracket 11, a clamping assembly 12, and a moving assembly 13.

The second preset position and the first preset position are set at intervals along the moving direction of the moving group 13. The measuring component 3 includes a measuring container 31, an image acquisition unit 32 and a replenishment group 33. The replenishment group 33 is connected to the measuring container 31. The image acquisition unit 32 is set outside the measuring container 31. A second opening is provided above the measuring container 31. The water supply component 4 includes a first pipeline 42, a second pipeline 43 and a liquid storage tank 41. The first pipeline 42 connects the high-pressure water gun 21 and the liquid storage tank 41. The second pipeline 43 connects the replenishment group 33 and the liquid storage tank 41. A first pump body 44 is provided on the first pipeline 42 and a second pump body 45 is provided on the second pipeline 43.

[0062] In this embodiment, the fixing component 1 is the basic support part of the device, used to fix and move the plant. The fixing bracket 11 is the skeleton structure of the device, used to support other components and ensure the stability and integrity of the device. The clamping assembly 12 is mounted on the moving assembly 13 and is used to clamp the stem or main trunk of the plant. The clamping assembly 12 has a clamping end 123, which can be adjusted according to the size and shape of the plant to ensure that the plant remains stable during rinsing and measurement. The moving assembly 13 is set on the fixing bracket 11 and is used to realize the horizontal movement of the clamping assembly 12 (and the plant). The moving assembly 13 can move the plant from a first preset position (rinsing position) to a second preset position (measurement position).

[0063] The rinsing assembly 2 is used to clean soil and impurities from plant roots, ensuring the roots are clean and undisturbed during testing. A high-pressure water gun 21 is installed inside the rinsing container 22, facing towards the roots. The high-pressure water gun 21 quickly and effectively removes soil and impurities adhering to the roots by spraying high-pressure water. The rinsing container 22 is located below the fixed support 11 and is used to hold water and impurities during the rinsing process. A first opening is provided at the top of the rinsing container 22 to facilitate the entry of plant roots; a drain outlet is provided at the bottom of the rinsing container 22 to drain the muddy water after rinsing. The rinsing container 22 is surrounded by a shielding flat structure to prevent mud and sand from splashing into the external environment.

[0064] The measurement component 3 is used for image acquisition and long-term monitoring of the cleaned root system. The measurement container 31, located below the fixed support 11, is used to hold the plant roots and the measurement liquid. A second opening is provided at the top of the measurement container 31 to facilitate the entry of the plant roots. The image acquisition unit 32 is located outside the measurement container 31 and is used to acquire images of the root system. The image acquisition unit 32 can be a camera or other optical device, capable of recording information such as root morphology and growth dynamics. The liquid replenishment group 33 is connected to the measurement container 31 and is used to replenish the liquid during the measurement process, ensuring that the roots are always submerged in the liquid surface and avoiding the influence of water evaporation on the measurement results.

[0065] The water supply assembly 4 provides water support for the rinsing and measurement processes. A first pipeline 42 connects the high-pressure water gun 21 and the storage tank 41, supplying rinsing water to the high-pressure water gun 21. A first pump body 44 is installed on the first pipeline 42 to control the water pressure and flow rate. A second pipeline 43 connects the replenishment assembly 33 and the storage tank 41, replenishing liquid to the measurement container 31. A second pump body 45 is installed on the second pipeline 43 to control the replenishment rate and volume. The storage tank 41 stores the water or liquid required for rinsing and measurement, ensuring continuous operation of the entire device.

[0066] In this embodiment, the first preset position and the second preset position can be simply understood as the two ends of the fixed bracket 11. In use, the plant is first placed on the clamping end 123 and moved to the first preset position. Then, the clamping assembly 12 moves downward so that the roots of the plant reach the rinsing container 22. Then, the high-pressure water gun 21 is turned on to control the high-pressure water gun 21 to spray water around the plant roots to complete the rinsing. The impurities and mud washed out can be discharged through the rinsing container 22. The rinsing container 22 is provided with a shielding flat plate structure around its perimeter to reduce the splashing of mud and sand to the outside during the rinsing process of the high-pressure water gun 21. Afterward, the clamping end 123 lifts the plant upward and moves the plant to the measuring container 31 at the second preset position. The plant is then lowered down so that the roots are submerged in the liquid surface, and the image acquisition unit 32 can be turned on for long-term image acquisition.

[0067] This embodiment achieves automatic movement and positioning of plant roots through the cooperation of the fixed component 1 and the moving assembly 13, reducing the tediousness of manual operation. The design of the high-pressure water gun 21 and the rinsing container 22 enables rapid and thorough cleaning of the roots, avoiding interference from soil and impurities on the measurement results. The combination of the measurement component 3 and the replenishment assembly 33 ensures that the roots are always in a suitable environment during the measurement process, supporting long-term monitoring. The layout of each component of the device is reasonable, with high space utilization. The water supply component 4 achieves automatic water supply through pipelines and a pump, reducing manual intervention and improving measurement efficiency.

[0068] Please refer to Figures 3 and 4. In some embodiments, the moving assembly 13 includes a first drive unit 131, a first support base 132, a second support base 133, a first lead screw 134, and a first lead screw nut 135. The first drive unit 131 is mounted on the fixed bracket 11; the first support base 132 is mounted on the fixed bracket 11; the second support base 133 is disposed opposite to the first support base 132 and is mounted on the fixed bracket 11; the first lead screw 134 is disposed between the first support base 132 and the second support base 133, and the end of the first lead screw 134 protrudes from the first support base 132 and is connected to the first drive unit 131 in a transmission manner; the first lead screw nut 135 is sleeved on the first lead screw 134, and a clamping assembly 12 is provided on the first lead screw nut 135.

[0069] The movable assembly 13 is an important component of the fixed assembly 1, used to enable the horizontal movement of the clamping assembly 12 (and the plant). The first drive unit 131 is the power source for the movable assembly 13, used to drive the first lead screw 134 to rotate, thereby moving the first lead screw nut 135 and the clamping assembly 12 on it. The first drive unit 131 can be a motor or other power device. A first support seat 132 is mounted on the fixed bracket 11. The first support seat 132 supports one end of the first lead screw 134, ensuring the stability of the first lead screw 134 during rotation. A second support seat 133 is disposed opposite to the first support seat 132, also mounted on the fixed bracket 11. The second support seat 133 supports the other end of the first lead screw 134, working with the first support seat 132 to ensure the stability and balance of the first lead screw 134. The first lead screw 134 is positioned between the first support seat 132 and the second support seat 133, with one end protruding from the first support seat 132. The first lead screw 134 is a key transmission component of the moving assembly 13. Its rotation drives the first lead screw nut 135 and its clamping assembly 12 to move. The end of the first lead screw 134 is connected to the first drive unit 131 and receives power input. The first lead screw nut 135 is sleeved on the first lead screw 134. The first lead screw nut 135 engages with the first lead screw 134 via threads. When the first lead screw 134 rotates, the first lead screw nut 135 moves axially along the first lead screw 134. The first lead screw nut 135 is equipped with the clamping assembly 12, which moves along with the first lead screw nut 135, thus achieving horizontal positioning of the plant.

[0070] After the first drive unit 131 is activated, it drives the first lead screw 134 to rotate. The rotation of the first lead screw 134 causes the first lead screw nut 135 to move along the axial direction of the first lead screw 134. Since the clamping assembly 12 is fixed on the first lead screw nut 135, the clamping assembly 12 and the plant on it will move with the movement of the first lead screw nut 135. By controlling the operating direction and time of the first drive unit 131, the clamping assembly 12 can be precisely positioned in the horizontal direction, thereby moving the plant to a first preset position (rinsing position) or a second preset position (measuring position).

[0071] In this embodiment, the precise horizontal movement of the clamping assembly 12 is achieved through the cooperation of the first lead screw 134 and the first lead screw nut 135, ensuring that the plant can accurately reach the rinsing and measurement positions. The first support base 132 and the second support base 133 jointly support the first lead screw 134, ensuring the stability and reliability of the moving assembly 13 during operation. The first drive unit 131 enables the operation of the moving assembly 13 to be fully automated, reducing manual intervention and improving operational efficiency. The design of the moving assembly 13 makes full use of the space of the fixed bracket 11, with a compact structure that is easy to install and maintain.

[0072] Please refer to Figure 4. In some embodiments, the clamping assembly 12 includes a support plate 121 and a second drive unit 122. The support plate 121 is disposed on the first lead screw nut 135. The second drive unit 122 is disposed on the support plate 121. The output end of the second drive unit 122 can reciprocate in the vertical direction. The clamping end 123 is disposed on the output end of the second drive unit 122.

[0073] The clamping assembly 12 is an important component of the fixing assembly 1, used to clamp the plant and adjust its position vertically. The support plate 121 is the basic structure of the clamping assembly 12, supporting the second drive unit 122 and the clamping end 123. The support plate 121 is connected to the first lead screw 134 via a first lead screw nut 135, and can move horizontally as the first lead screw nut 135 moves. The second drive unit 122 is the power source for the clamping assembly 12, driving the clamping end 123 to reciprocate vertically. The second drive unit 122 can be a motor, cylinder, or other power device, and its output end can move vertically up and down. The clamping end 123 is located on the output end of the second drive unit 122. The clamping end 123 is used to directly clamp the stem or main trunk of the plant. The clamping end 123 can be adjusted according to the size and shape of the plant to ensure stability during rinsing and measurement.

[0074] When the vertical position of the plant needs to be adjusted, the second drive unit 122 is activated, driving its output end to move vertically. Since the clamping end 123 is fixed to the output end of the second drive unit 122, the clamping end 123 moves up and down with the movement of the output end, thereby adjusting the vertical position of the plant. By controlling the operating direction and time of the second drive unit 122, precise positioning of the clamping end 123 in the vertical direction can be achieved, thereby accurately moving the plant's roots into the rinsing container 22 or the measuring container 31.

[0075] The second drive unit 122 enables precise vertical movement of the clamping end 123, ensuring accurate entry of plant roots into the rinsing container 22 or the measuring container 31. The vertical movement of the clamping end 123 allows for more flexible and adaptable position adjustments for the plant during different operational steps. The combination of the support plate 121 and the second drive unit 122 ensures the stability and reliability of the clamping assembly 12 during operation. The second drive unit 122 fully automates the operation of the clamping assembly 12, reducing manual intervention and improving operational efficiency. The design of the clamping assembly 12 fully utilizes the space of the support plate 121, resulting in a compact structure that facilitates installation and maintenance.

[0076] Please refer to Figure 3. In some embodiments, the clamping end 123 is provided with a first opening groove 124, which penetrates the clamping end 123, and the plant is placed in the first opening groove 124.

[0077] The clamping end 123 is the distal portion of the clamping assembly 12, directly contacting the plant and used to secure the plant's stem or trunk. By clamping the plant's stem or trunk, the clamping end 123 ensures the plant remains stable during rinsing and measurement, preventing displacement or shaking due to movement or the action of the rinsing water flow. The first opening groove 124 is used to accommodate the plant's stem or trunk. The plant is placed within the first opening groove 124 and secured by the clamping force of the clamping end 123. The design of the first opening groove 124 can be adjusted according to the plant's diameter and shape to ensure the plant is securely fixed within the clamping end 123.

[0078] When the plant needs to be secured, the stem or main trunk of the plant is placed into the first opening slot 124. The plant is securely fixed in the clamping end 123. During rinsing and measurement, the clamping end 123 can be moved vertically under the control of the second drive unit 122, thereby adjusting the position of the plant so that its roots can accurately enter the rinsing container 22 or the measurement container 31.

[0079] In this embodiment, the design of the first opening groove 124 allows the plant stem or main trunk to be securely fixed in the clamping end 123, preventing loosening or displacement during rinsing and measurement. The fixing and release of the plant can be accomplished through simple placement and clamping operations, reducing operational complexity and time costs.

[0080] Please refer to Figures 1 and 2. In some embodiments, the bottom of the rinsing container 22 is provided with a first inclined surface 221, which is inclined in a first direction; the bottom of the rinsing container 22 is also provided with a drain trough 222, which is connected to the edge of the first inclined surface 221 and communicates with the outside.

[0081] The rinsing container 22 is located below the fixed support 11 and positioned in a first preset location. It is used to contain plant roots and water and impurities generated during the rinsing process. The rinsing container 22 is the core component of the rinsing assembly 2, providing rinsing space and collecting the rinsing mud and water and impurities. The design of the first inclined surface 221 allows the mud and water generated during rinsing to flow naturally along the inclined surface, facilitating collection and discharge. The inclination angle and direction of the first inclined surface 221 can be designed according to actual needs to optimize drainage. The drainage trough 222 is located at the bottom of the rinsing container 22, connecting to the edge of the first inclined surface 221 and communicating with the outside. The drainage trough 222 collects the mud and water flowing down from the first inclined surface 221 and discharges it from the rinsing container 22. The design of the drainage trough 222 ensures that the mud and water generated during rinsing can be discharged quickly and efficiently, preventing accumulation inside the container.

[0082] Once the plant roots enter the rinsing container 22, the high-pressure water gun 21 is activated, spraying high-pressure water around the roots to wash away the attached soil and impurities. The muddy water and impurities generated during rinsing flow along the first inclined surface 221 under gravity and eventually collect in the drainage trough 222. The drainage trough 222 discharges the muddy water and impurities from the rinsing container 22, ensuring the container remains clean and preventing impurities from interfering with subsequent measurement processes.

[0083] In this embodiment, the design of the first inclined surface 221 and the drainage channel 222 enables the mud and impurities generated during the rinsing process to be discharged quickly and efficiently, preventing them from accumulating inside the container. The bottom design of the rinsing container 22 makes full use of gravity, simplifying the drainage structure and reducing the complexity and maintenance costs of the device.

[0084] Referring to Figure 1, in some embodiments, the rinsing assembly 2 further includes a first guide plate 23 and a collection tank 24. The first guide plate 23 is disposed below the drain trough 222; the collection tank 24 is disposed below the first guide plate 23 and is used to collect wastewater discharged from the first guide plate 23.

[0085] In this embodiment, the first guide plate 23 is used to guide the wastewater flowing out of the drainage trough 222 towards the collection tank 24. The first guide plate 23 is typically designed as an inclined structure or has a flow channel to ensure that the wastewater can flow smoothly into the collection tank 24, preventing splashing or stagnation inside the device. The collection tank 24 is used to collect the wastewater discharged from the first guide plate 23. The collection tank 24 is typically designed as a container-like structure, capable of holding a certain amount of wastewater for subsequent treatment or discharge.

[0086] During the rinsing process, the high-pressure water jet 21 washes away the soil and impurities from the roots, forming muddy water. The muddy water flows through the first inclined surface 221 to the drainage trough 222 and is discharged from the drainage trough 222. The discharged muddy water is guided by the first guide plate 23 and flows into the collection tank 24. The collection tank 24 centrally stores the wastewater for subsequent treatment or discharge.

[0087] In this embodiment, the design of the first guide plate 23 and the collection tank 24 allows for the centralized collection of wastewater generated during the rinsing process, preventing environmental pollution or disruption to the normal operation of the device. The first guide plate 23 effectively guides the wastewater towards the collection tank 24, preventing splashing onto the outside of the device or other components. The collection tank 24 makes wastewater treatment more convenient, reducing the frequency and difficulty of manual cleaning.

[0088] Please refer to Figures 1 and 2. In some embodiments, the rinsing assembly 2 further includes a third support 25 and a rotary drive unit 26. The third support 25 is disposed below the rinsing container 22 and has a first extension end on which a high-pressure water gun 21 is provided. The rotary drive unit 26 is disposed below the third support 25 and is used to drive the third support 25 to rotate.

[0089] The third support base 25 supports and secures the high-pressure water gun 21 and provides it with rotational functionality. The third support base 25 has a first extension end on which the high-pressure water gun 21 is mounted, ensuring that the high-pressure water gun 21 can rotate and rinse around the plant roots. The rotation drive unit 26 drives the third support base 25 to rotate, thereby causing the high-pressure water gun 21 to rotate and rinse around the plant roots. The rotation drive unit 26 can be a motor or other rotational power device, capable of precisely controlling the rotation speed and angle.

[0090] Once the plant roots enter the rinsing container 22, the rotary drive unit 26 is activated, driving the third support base 25 to rotate. The rotation of the third support base 25 causes the high-pressure water gun 21 to rotate and rinse around the plant roots, ensuring that the roots are cleaned evenly in all directions. The high-pressure water jet from the high-pressure water gun 21 can quickly remove soil and impurities attached to the roots, and the rinsed muddy water is discharged through the drain outlet of the rinsing container 22.

[0091] This embodiment achieves comprehensive root cleaning through the cooperation of the rotary drive unit 26 and the high-pressure water gun 21, significantly improving cleaning efficiency. The rotation function of the high-pressure water gun 21 ensures that the roots are evenly rinsed in all directions, avoiding cleaning dead spots. The rotary drive unit 26 automates the rinsing process, reducing manual intervention and improving operational efficiency. The design of the third support 25 and the rotary drive unit 26 makes full use of the space under the rinsing container 22, resulting in a compact structure that is easy to install and maintain.

[0092] Please refer to Figures 1 and 5. In some embodiments, the replenishment assembly 33 includes a liquid level sensor 331, a replenishment pipe 332, and a control unit. The liquid level sensor 331 is disposed on the inner wall of the measuring container 31. The replenishment pipe 332 is connected to the bottom of the measuring container 31 and to the second pipeline 43. The control unit is electrically connected to the liquid level sensor 331 and the second pump body 45.

[0093] The liquid level sensor 331 is used to monitor the liquid level in the measuring container 31 in real time. When the liquid level is lower than a preset value, the liquid level sensor 331 sends a signal to the control unit to trigger a liquid replenishment operation. The liquid replenishment pipe 332 is used to transport liquid from the storage tank 41 to the measuring container 31. The liquid replenishment pipe 332 is designed to ensure that liquid can be quickly and evenly replenished into the measuring container 31, avoiding excessive liquid level fluctuations. The control unit is the core control part of the liquid replenishment group 33, used to receive the signal from the liquid level sensor 331 and control the start and stop of the second pump 45 according to preset conditions. The control unit can be a microcontroller, PLC, or other control device, capable of achieving automated control.

[0094] When the liquid level in the measuring container 31 falls below a preset value, the liquid level sensor 331 sends a signal to the control unit. Upon receiving the signal, the control unit activates the second pump 45 to pump liquid from the storage tank 41 through the second pipeline 43 and the replenishment pipeline 332 into the measuring container 31. When the liquid level returns to the preset value, the liquid level sensor 331 sends a signal to the control unit again, and the control unit shuts off the second pump 45, stopping the replenishment.

[0095] This embodiment achieves automatic adjustment of the liquid level in the measuring container 31 through the cooperation of the liquid level sensor 331 and the control unit, ensuring that the roots are always submerged in the liquid. The liquid level sensor 331 can monitor the liquid level in real time, and the control unit can accurately control the amount of liquid replenishment based on the monitoring results to avoid the liquid level being too high or too low. The automated design of the liquid replenishment unit 33 reduces manual intervention and improves operational efficiency. The liquid replenishment pipe 332 is connected to the bottom of the measuring container 31 to ensure that the liquid can be quickly and evenly replenished into the measuring container 31, avoiding excessive fluctuations in the liquid level.

[0096] Please refer to Figures 1 and 5. In some embodiments, the measuring component 3 further includes a fourth support 34 and a background plate 35. The fourth support 34 is disposed below the measuring container 31 and has a second extension end. The background plate 35 is disposed on the second extension end and is disposed opposite to the acquisition end of the image acquisition unit 32.

[0097] The fourth support 34 supports and fixes the background plate 35, ensuring that the background plate 35 is positioned opposite to the acquisition end of the image acquisition unit 32. The fourth support 34 has a second extension end, on which the background plate 35 is mounted. The background plate 35 provides a uniform background color or pattern, ensuring that the image acquisition unit 32 can clearly capture the morphology and structure of the plant root system. The design of the background plate 35 reduces interference during image acquisition and improves image quality.

[0098] Once the plant roots are immersed in the liquid in the measuring container 31, the image acquisition unit 32 begins to acquire images of the roots. The background plate 35 provides a uniform background color or pattern to ensure that the image acquisition unit 32 can clearly capture the morphology and structure of the roots. By setting the background plate 35, interference during the image acquisition process can be reduced, image quality improved, and the morphology and growth dynamics of the roots can be analyzed more accurately.

[0099] In this embodiment, the background plate 35 provides a uniform background color or pattern, ensuring that the image acquisition unit 32 can clearly capture the morphology and structure of the root system, thus improving image quality. The design of the background plate 35 reduces interference during image acquisition and prevents cluttered backgrounds from affecting image analysis. The combination of the fourth support 34 and the background plate 35 ensures the stability and reliability of the background plate 35, preventing shaking or shifting during image acquisition. The background plate 35 makes the image acquisition process more convenient and reduces the tediousness of manually adjusting the background.
